You can try connecting the gray wire to BCM amd see if it will light up the indicator light on the dash. GRAY WIRE TO PIN # 12 WHITE BCM CONNECTOR. Let us know if it works plz.
Hey bro so I tried the relay setup and CAN'T get it to work don't know what i am doing wrong... Om the relay diagram you have the yello wire connected to 12v output there is no power. And on the wire where the gray wire connects to relay it has power always. I checked my connections with the diagram. So not sure what the issue. Can you help?
One more question. Do you known if is possible to get the dash light indicator to illuminate with this set up? Or it one of them that BCM has to programmed?
Thanks for the response. Yes I already have the harness installed made it my self just like Phil's. So I dont connect the wires to the BCM they will go to the relays bank correct???
Hey bro so can It be done with 1 relay or it has to be done with all 5 of them?? I bought the switch but my truck its not programmed for it to work and i really dont want to pay the dealership to turn it on. If I can just do it with relays it be cool...
Can you provide a link for the relays?
Well i bought the buttons for my truck because i found out it had the heating elements. All of a sudden the passengers sest would get hot. I didn't believe my brother once he told me untill in was sitting on it then it turned on by itself. So i bought the buttons and yes it was wired but the buttons dont turn ON or OFF.
I will check with dieselworks thanks for the response.
